Control Structure In Flux Sensorless (Fc 302 Only); Control Structure In Flux With Motor Feedback - Danfoss FC 300 Design Manual

3. Introduction to FC 300

3.2.5. Control Structure in Flux Sensorless (FC 302 only)

Control structure in flux sensorless open-loop and closed-loop configurations.

In the shown configuration, par. 1-01
par. 1-00 is set to "Speed open-loop [0]." The resulting reference from the reference handling
system is fed through the ramp and speed limitations as determined by the parameter settings
indicated.
An estimated speed feedback is generated to the speed PID to control the output frequency.
The speed PID must be set with its P, I, and D parameters (par. group 7-0*).
Select "Process [3]" in par. 1-00 to use the process PID control for closed-loop control of speed
or pressure in the controlled application. The process PID parameters are found in par. group 7-2*
and 7-3*.
